3.x versions of this module are marked as compatible with Drupal 10, however, the .install file is referencing the Simple Google Maps module which does not have a Drupal 10 compatible version.
Go to the opigno_calendar.install (line 21)
// Enable <code>simple_gmap module.
if (!\Drupal::moduleHandler()->moduleExists('simple_gmap')) {
\Drupal::service('module_installer')->install(['simple_gmap']);
}
Remove the reference to Simple Google Maps module to the .install file.

The latest version of Simple Google Maps is compatible with Drupal 10, so I guess this issue can be closed as 'works as designed'.
Drupal 11 release of simple_gmap is available now
